GRAIN-TIGHT BOX-CAR.

v To all whom it may concern referred to Be it known that 1, PETERPaRKE, a citizen of the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have nvented certain new anduseful Improvements in Grain-Tight Box-Cars, of which the following is aspecification.

Where, as is usual, ordinary box cars are used in carrying grain, leaksare liable to develop between the flooring and side sheathing due to theopening of the joint with the shrinkage of the lumber employed in theconstruction of the car and the spreading of the same under the weightand shifting of the lading and much difficulty has been experienced inthe effort to obtain and maintain a grain-tight joint at the junction ofthe floor and siding.

It has been proposed to prevent the separation of the side sheathing andflooring by the employment of a side sill having an upwardly extendingintegral tenon or tenons, or a flanged plate superposed on the sill, theflanges or tenons in either case seated in the grooves in By myconstruction I-secure the desired result of a permanently grain-tightjoint and at the same time avoid the difficulties by providing arelatively thin metal plate overlying the sill and having a resilientupwardly extending inwardly inclined flange seated within a recess ofthe sheathing greater than the thickness of the metal whereby the upperwall of the recess is caused to overhang the upper end of the flange andprevent ingress of moisture while theflange has suflicient spring actionto effect Specification of Letterslatent.

a resilient connection between the sheathing and flooring which willinsure against a splitting of the board under sudden shock whilemaintaining a tight joint as the lumber shrinks. I also provide a secureanchor age of the floor by extending the plate inwardly beyond the inneredge of the side sill and bolting the floor boards to the plate, whichis in turn bolted to the sill, thus en-' abling the floor to beadequately supported by means of channel sills having flanges of lesswidth than would otherwise be necessary.

Other advantages of construction and operation from the standpoint ofconvenience, economy and efliciency will be apparent to those skilled inthe art of car building from the subjoined detailed description basedupon a preferred embodiment of the invention as set forth for purposesof illustration in the accompanying drawing, wherein- Figure 1 is afragmentary view of a car body in transverse vertical section; and Fig.2 is a similar section on an enlarged scale. 7

In the drawings the numeral 11 designates one of the cross "bearers ofthe car, 12 a side sill of channel cross section, 13 the flooring,

14 the side sheathing, and 15 the side supporting posts, all of theusual construction. 80

superposed upon the upper flange 12 of the side sill and extendinglongitudinally thereof from the door post to the corner ofthe car, orfrom corner to corner at the end of the car and beneath the llne ofjunction between the flooring and side sheathing, is a relatively thinmetal plate 16 having along its outer edge an upwardly extendinginwardly inclined flange 17 which bears upon the outer face of the lowersheathing board 14 and preferably Within a recess 18 of greater depththan the thick ness of the metal whereby the upper wall 19 of the recessoverhangs the upper edge of the flange to a material extent. Thehorizontal portion of this plate .16 has a width considerably greaterthan the flange 12 of the sill and extends inwardly beyond the inneredge of the sill suilicien'tly to provide recesses for the reception ofbolts 20 by 1 0 n'ieahs 5f which the flooring boards 13 are firm-1ysecured to the plate, the plate being in turn secured to the flange 12of the sill by means of bolts 21. The securing of the floor boards tothe inner edge of the plate obviates the necessity of employing a sillwith a horizontal flange sufliciently wide to enable the flooring to besecured directly to the sill, thus cheapening the construction Withoutimpairing its efiiciency.

In practice the line the flooring and sheathing is sealed by means ofgum-asphaltum or the like, as indicated at 22, and when assembled theflange 17 of the plate exerts spring pressure inwardly upon the sidesheathing along the upper-edge of said flange, the lower portion of theflange beingout of contact with the board. Thus as the boards of theflooring and sheathing shrink the spring flange serves to maintain aclose joint between the two while there is suflicient resiliency in theflange to take up the shock of shifting lading and prevent a splittingof the lower sheathing board at or above the flange as would result werethe flange l7 absolutely rigid. The housing of' the upper edge of theflange beneath recess also serves to entrance ofi rain or snow behindthe flange and thusprevents the rotting of the board along its loweredge.

While the invention is illustrated as applied longitudinally of the caralong the side sill, it is equally applicable and could be employedalong the end sill of the car to effect a grain tight connection betweenthe flooring boards and side" sheathing at the ends of the car.
